What category are pyramidal cells in the crebral cortex?
What is the area between the grey matter and the edge of the spinal cord?
lishour fasiculus
(pain and temp)
From the hemispheres the CSF flows into the ventricles between the thalami and the hypothalami
: the 3rd ventricle
From the 3rd, the CSF flows into a thin ventricle runs from 3rd to midbrain:
this is just extra
The flow of CSF flows from lateral to intraventricular foramen to 3rd ventricle to aqueduct to 4th. From the 4th, CSF goes outside the brain and into sinuses. CSF forming in the ventricles flows outside the brain in the arachnoid space to get to the sinuses.

Below right T3 and T4
conscious proprioception is coming up what?
posterior funiculus
prefrontal functions
planning, working memory, judgement, sequencing, initiative.

Astero agnosis is the answer
what is the gyrus at the end of the lateral fissure
fibers originating in motor cortex coming down in what tract?
Cortico-spinal and cortico bulbar
in general where does the cortico-bulbar tract go? Specifically?
Cranial nerve motor nuclei
7th cranial nerve
2 main divisions of prosencephalon
diencephalons and telencephalon.
Rombincephalon separate into which two?
metencephalon and myelencephalon
myelencephalon gives rise to what?
Which of these do viscreal efferent fibers innervate?
Axon hillock

Peripheral nerve does NOT have?
fibers from pyramidal cells
What is FALSE about dendrites?
dendreites convey info away from soma
HOw do we tell healhty nerve cell bodies?
Nuecleus is in the center
How about damaged nerve cells?
nucleus becomes eccentric, as well as nissl
What is myeline?
